Changing stereo to navigation in verso
 

Hi

I have a 2011 verso with boring stereo(ID no:w53850 model:86120-0F090 ref no:CQ-JS7070G).
I bought used new navigation from higher model(86120-64040 ref no:CQ-HS70F0AJ), it works okay, exept not getting microphone input.
Does anyone have the pinout of the connection from these models, that can help me with connecting this properly.
Also, does anyone know where to get map update for this model, without going to dealer, i understand that i need to connect harddrive to computer to transfer the new software, but which software is compatible, this is not known to me??
